The BA488CF-P
Fieldbus Display is an intrinsically safe instrument that can
display up to eight fieldbus process variables. Eleven selectable
standard screen formats contain one, two, three, four or eight
variables, with units of measurement, tag descriptions and bargraphs
on some screens.
Powered by the fieldbus the BA488CF-P only
requires a 2-wire connection, no additional power supply Zener
barriers or galvanic isolators are required. The high contrast 86 x
45mm liquid crystal display incorporates a green backlight that is
also powered from the fieldbus enabling the display to be read in
all lighting conditions from full sunlight to total darkness.
Simple commissioning results from the use of
standard display formats. Apart from loading the BA488CF-P
configuration files onto the system host and selecting the fieldbus
variables to be displayed, no programming is required. Configuration
of the BA488CF-P Fieldbus Display is performed via the fieldbus and
the instrument front panel push buttons.
ATEX, FM & IECEx intrinsic safety
certification allows the BA488CF-P to be installed in gas hazardous
areas worldwide. The two fieldbus terminals comply with the Fieldbus
Intrinsic Safety Concept (FISCO) simplifying system design and
documentation, although connection to non-FISCO intrinsically safe
segments is possible using the entity concept. This allows a
BA488CF-P to be directly connected to almost any hazardous fieldbus
providing the segment can supply the 25mA consumed by the display.
Six optional local
alarm outputs may be linked to any of the displayed variables. Each
isolated single pole solid state output may be conditioned as a
combined high and low alarm, or as just a high or low alarm. All the
outputs comply with the requirements for simple apparatus allowing
them to switch any certified intrinsically safe load such as a
sounder, lamp or solenoid valve. Alarm configuration and the alarm
set point adjustment is performed via the BA488CF-P front panel push
buttons, as the local alarms are not accessible from the fieldbus
system host
The six push buttons on the front of the
instrument may be used for returning operator acknowledgments or
controls to the fieldbus host. If larger industrial switches are
required for these operator controls, up to six external push
buttons may be connected to the BA488CF-P. When the external
switches are activated, the front panel push buttons may be disabled
or operated in parallel with the external switches.
Comprehensive documentation includes a PROFIBUS
Interface Guide.
For field mounting applications see
the BA484DF-P datasheet. This instrument has a similar electrical
specification but is housed in a robust IP66 GRP enclosure suitable
for external mounting.
